Title: Terminal equipment for power control
Inventor: MIMURO YASUAKI
IPC: G06F17/40
Filed: 1993-06-25
Abstract: PURPOSE:To make it possible to perform the smooth time division multiple transmission of a load data collection by returning the data of a control unit which is periodically collected and stored to a master machine by request. CONSTITUTION:A transmission unit 13 periodically performs a data request to a braking unit 14 and the unit 14 transmits the data to the unit 13 each time the data is requested. The unit 13 updates and stores the transmitted data. If a data request is received from a master machine 10, the unit 13 instantaneously returns storage data to the master machine. When the state change exists in the load of a motor and a braker, etc., the unit 14 performs a state change notification for the unit 13, and the unit 13 transmits this state change to the master machine 10 by an interruption. As a result, the delay due to the cycle time of the periodic data request to the unit 14 by the unit 13 can be eliminated. Thus, the load data collection of the master machine can be smoothly performed by a time division multiple transmission.
